It looks like a lovely house that's been rented out and nobody has ever added any personality because they knew they wouldn't be staying.
Totally agree about adding colour. Towels, cushions, something pretty hanging on the coat hooks in the hallway, rugs, picture, huge vases of flowers on tables, fruit and flowers in kitchen.
The first picture hints that if you buy this place there's work to do from the outset. Weeds on the drive, patchy grass, a drive that looks like a banger of a car has been parked on it for a decade. Jet wash the drive, weed, water lawn, add a couple of pots with colourful flowers.
I can't comment on price although I always find the range thing strange. I mean if you're saying £375 - 400,000 nobody is going to offer 400.
Speaking personally, I like your house very much, but the single worst thing about it in my opinion is the extent to which it's so hugely overlooked. Is there anyway you could get pictures that lessen the impact of that because I think if someone saw how much your house has to offer (excellent kitchen, lots of space, big back garden) they might fall in love with it enough to think the overlooked nature of it doesn't matter - or at least to move in and plant a fast growing hedge.
